Positioning device, positioning method and storage medium storing program

摘要

A positioning device for obtaining position data of a plurality of points on a movement route, including a positioning unit that can measure a present position; a movement measuring unit for measuring a relative positional change; a position calculating unit for calculating position data of the plurality of points on the movement route on the basis of position data of a first reference point and positional change data obtained through measurement of the movement measuring unit; and a correcting unit for correcting the position data of at least one of the plurality of points calculated by the position calculating unit on the basis of difference information representing difference between a position represented by the position data calculated by the position calculating unit and a position represented by a positioning result of the positioning unit with respect to any second reference point on the movement route.
